While conventional disc cutters apply high compressive loads to fracture rock, the ODC system exploits the tensile weakness of rock through "undercutting". The ODC was the brainchild of design engineer David Sugden who collaborated with Australia's Cooperative Research Centre for Mining Technology and Equipment.

The cutter advanced by cutting the rock model at a rate of 1.4 m/s at a depth of 5 mm. Total of 150 monitoring points were installed inside the rock model beneath the cutting path, from 1 to 15 mm (see Fig. 5b). The strain rates in the x-, y-, and z-directions were recorded and plotted against monitoring distances.

C ontinuous mining systems have been established in coal and soft rock mining for about a century now and the technology to cut through hard rock has been successfully used in civil engineering projects since the late 1950s. One would think that by now, continuous hard rock mining would also be a reality but it is not. The possibility of …

Cut - A horizontal channel made by removing a section of rock for mining purposes. Cut-and-fill - A method of stoping in which ore is removed in slices, or lifts, and then the excavation is filled with waste or ore before the subsequent slice is extracted. Cut-off grade - The lowest grade of mineralized material that qualifies as ore in a given ...

The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.

Tunnel boring machine (TBM) has been in focus for the last few decades and is currently the most preferred excavation method for metro, hydro and irrigation tunnels. Tunnelling in hard and abrasive rock conditions, in particular, is adversely affected by a very low advance rate coupled with increased TBM disc cutter failures and cutterhead …
